6. Threesome With Another Woman

A threesome fantasy can say a lot about a lady -- especially when it comes to what type of threesome she's most into daydreaming about. The idea of adding another partner to the mix can feel overwhelming. But asking another woman to join in on the fun takes that pressure down a notch in a way, because you're dealing with a person who feels familiar without having to get to know them. "Depending on how they are oriented, some women prefer [MFF] because it allows her to share dominance with another that feels safe," says Dr. Van Kirk, "Also, she may be more attracted to having another female to 'play' with versus a male."

Sometimes (but not always), a threesome fantasy involving another woman as the guest star can mean that there's some bi-curiosity your lady is interested in exploring -- but wants you there with her for the experience. "Many of my bi-curious clients have this fantasy," says Corrine, "and have stated the reason as they'd like to explore their sexuality with their male partner or with a partner that they are already familiar with."

What Real Women Say:

"There's this gorgeous Puerto Rican woman who teaches class at the boxing gym that my boyfriend and I work out at on the weekends," says Cassie, 22. "Her body is slamming, total fit body goals. I've never had any kind of sexual encounter with a woman before, but in my fantasy I imagine her approaching me after class in the locker room after everyone else has left -- except for my boyfriend, who's waiting outside. She brushes against me, 'accidentally,' and then tells me how good I did in class, and that I worked really hard today. She starts massaging my shoulders as a reward for my hard work. Then her hands move down my thighs, and finally she slips her hands down my yoga pants and starts gently massaging my clit. It feels so good that I cry out -- and my boyfriend runs into the locker room to make sure that I'm OK. He sees whats going on, and approaches both of us. He does me from behind while the instructor is still in front of me caressing every part of my body. When it's over it isn't weird at all. She gets her stuff together, smiles at us on her way out and says, 'Same time next week?'"
